Ridiculous data charges

<p>I am disputing the high data charge on my account which has been going on for a few days now as I recharged with 30MB on my number ********** 979 yesterday and I have only been on whatsapp where I was not transmitting or sending any big files and have not received any. My data has been turned off for the good part of today and I am not running any apps in the background which I have turned off the apps to only run over WiFi. I am extremely unhappy with being over charged for only Whatapp.</p> <p><br />This is really getting out of hand.<br />May I have feedback with the query.</p>
